PUMP.

Specification of Letters Patent.

Patented Nov. 25, 1913.

Application filed December 21, 1912. Serial No. 738,061.

To all whom it may concern:

Be it known that I, FRANK A. GARvnr, a citizen of the United States of America, residing at Lynxville, in the county of Crawford and State of Wisconsin, have invented certain new and useful Improvements in Pumps, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a pump, which is intended to be used in connection with a well.

The principal object of the invention is to provide a device which will cause the pump to operate easily and to overcome the weight of the sucker rod when the buckets are filled with water.

Another object of the invention is to provide an improved type of tube in which the sucker rod operates.

In the accompanying drawing :Figure 1 is a vertical sectional view through a pump formed in accordance with this invention. Fig. 2 is a perspective view of the top portion of the pump to show the manner in which the spring is adjusted. Fig. 3 is an enlarged fragmentary view of the lower end portion of the pump rod to show the manner of connecting the rod with the sucker rod, and the manner of connecting the lower end of the spring with the pump rod. Fig. 4: is a sectional view along the line 1, in Fig. 3. Fig. 5 is an enlarged sectional view through the upper end portion of the tube in which the spring is positioned.

Referring to the accompanying drawing it will be seen that this pump is positioned in a well 10 and comprises a pipe 11 which extends to the bottom of the well, the sucker rod 12 being mounted in this pipe 11. The upper end of the sucker rod is connected with the threaded lower end 14 of the pump rod 15 by the coupling 13, thus permitting the pump rod to be disconnected from the sucker rod when so desired. A tubular spring casing 16 is connected with the pipe 11 by means of a coupling 17 and has its upper end in threaded engagement with a collar 18 which is carried by the base 19 of the pump. This base 19 is provided with an enlarged lower portion 20 which incloses the mouth of the well. A spring 21 is mounted in the casing 16, and surrounds the pump rod 15 with its lower end formed into an eye 22 through which the rod 15 passes. Abutment nuts 22 are provided so that the upward movement of the spring will be limited. The upper portion 23 of the pump is in threaded engagement with the collar 18 and is provided with an enlarged upper end portion 24 which forms a waterhead so that in case the water is raised faster than it can flow out of the spout 25 it will back up in this head. A cap 26 fits onto the upper end portion of the pump and is held in place by means of a set screw 27, thus preventing accidental removal of the cap and also prevents the cap from having any tendency to rotate. The pump rod 15 passes through a rectangular opening 28 and since this pump rod is rectangular it will, therefore, be seen that the pump rod cannot rotate and cause its lower end to be disconnected with the sucker rod. The spring 21 passes into the upper portion of the pump to a point intermediate the height of the water head 24: and terminates in a rod 29 which passes through an opening formed in the cap 26. The outer end portion 30 of the rod 29 is threaded and a nut 31 is provided so that the rod may be adjusted, thereby regulating the spring. A handle 32 is pivotally connected with the link 33 and has its inner end pivotally connected with the pump rod by means of the pivot pin 34. The link 33 is pivotally connected with the lower end of a guiding arm 35 provided with an eye 36 through which the pump rod 15 passes.

When operating this pump the sucker rod is drawn upwardly by operating the handle and this forces water through the pipe 11 and casing 16 into the upper portion of the pump. The water will be pumped into this upper portion faster than it can pass out through the spout 25, and therefore, it will accumulate in the water head 24 thus causing the water which comes out of the spout to have considerable force. The spring 21 assists in supporting the pump rod and sucker rod and prevents the weight of the water in the bucket from causing the pump to work hard. This spring also has a tendency to break up the water in the casing 16 into a number of parts so that the pipe will not burst should the water freeze. It should also be noted that by this construction that the spring can be adjusted very readily by the nut 31 and that the upper portion of the pump can be removed in order to repair the upper portion and that the pump rod can be readily removed from the sucker rod by removing the cap 26 and after disconnecting the handle from the pump rod turn the pump rod until the lower end 14: is disconnected from the socket 13.

Having thus described the invention what is claimed as new, is

1. A pump comprising a body portion, a

pump pipe, a spring casing having one end connected with said pipe and the upper end connected with said body portion, a sucker rod in said pipe, a pump rod passing through said spring casing and having its inner end removably connected with said sucker rod, a spring having its lower end connected with said pump rod and its upper end adjustably supported by said body portion, and operating means connected with said pump rod.

2. A pump comprising a body portion, a water tube, a sucker rod in said water tube, a spring casing removably connected with said water tube and having its upper end portion removably connected with said body portion, a pump rod passing vertically through said body portion and having its lower end threaded and fitting into a socket at the upper end of said sucker rod, a spring positioned in said casing surrounding said .pump rod and having its lower end connected with said pump rod, the upper end of the spring terminating in a rod having a threaded end passing through the upper end of said body portion, an adjusted nut threaded upon the outer end portion of said rod, and operating means connected with said pump rod.

3. A pump comprising a body portion having upper and lower sections, a spring casing passing through said lower section and having its upper end in threaded engagement with an enlarged threaded collar in said body portion, a water tube connected with the lower end of said spring casing, a sucker rod positioned in said water tube, a pump rod passing through said spring casing and connected with said sucker rqd, a spring connected with said sucker rod and the upper portion of said body portion, and operating means connected wlth said pump rod.

4. A pump comprising a body portion provided with an outlet spout intermediate its height and having an upper portion enlarged to form a water head, a water pipe, a spring casing connected with said body portion and supporting said water pipe, the upper end of said casing being positioned in alinement with the lower edge of said out let spout, a sucker rod in said water pipe, a pump rod passing through said spring casing and connected with said sucker rod, a spring passing through said spring casing with its lower end connected with said pump rod, the upper portion of said spring extending to a point adjacent the lower end of said water head and terminating in a rod adjustably connected with said body portion, and operating means connected with said pump rod.

5. In a pump, a casing, a pump rod passing through said casing, and a spring in said casing surrounding said pump rod and having its lower end secured thereto, the

7 upper portion of said spring forming a rod having a threaded end portion whereby said spring may be adjustably connected with.

the body portion of a pump.

6. In a pump, a pump rod having a threaded lower end portion, abutment nuts upon the lower end portion of said pump rod, and a spring surrounding said pump rod and having its lower end formed into an eye through which said pump rod passes as far as permitted by said abutment nuts, the upper end of said spring terminating in a rod having means adjacent its ends for adjustably connecting it with a support.

In testimony whereof I hereunto aflix my signature in presence of two witnesses.
